VSPECIFICATION forming part of Letters Patent No. 294,736, dated March 4, 1884,Y

` Application filed December 111, iSES. (Medel.)

T all whom rit may concern,.-

Be it known that I, HENRY A. HYLE, of Redwood, in the county of Jefferson and State of New York, have invented a new and Improved Vise, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, icrming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of my new and improved vise. Fig. 2 is a plan view of the same, and Fig. 3 is a perspective view `of one of the grasping blocks or cylinders.

The invention will lirst be described in connection with the drawings, and then pointed out in the claims.

Referring to the drawings, A A represent the jaws of the vise, and B represents the operating-screw. The jaws A are correspondingly recessed, as shown vat a, in such manner as to cut away a part of the faces of the jaws, as shown in Fig. l; and in the recesses 'c are placed the grasping blocks or cylinders G C, which protrude slightly from the openings in the faces of the jaws, for grasping and holding any object placed in the vise. C C are duplicates of each other, and are by preference made of chilled cast-steel. They arel held against endwise movement in the recesses a by the horseshocshaped plates D, secured to the side surfaces of the jaws A, and they are adapted to be revolved in the recesses a by the handles b; and they are each formed with the iiat face c, for holding iiat objects;

with the triangular longitudinal groove d, forA holding square or angular objects; with the large and small concaved grooves ef, for holding round objects; with the narrow slots g h, for holding narrow and fiat or edged objects 5 with the shallow, short, triangular, and concaved recesses j, for holding pointed objects; and they are also formed with the angug lar and ccncaved transverse recesses 7s Z, for holding objects in vertical position. The slot g in each of the cylinders O is` chamfered oli at its ends, as shown at imi, also for holding pointed objects. The plates D, besides serving to hold the cylinders C against-longitudinal movementin the recesses a, also serve to prevent dust, iilin gs, 85e., from entering the rerlhe cylinders y cesses a and obstructing the'free revolution of the cylinders in the recesses.

m m represent pins passed through orifices made in the jaws A, and adapted to enter holes n, made in the cylinder C, for keying the cyl inders in any desired position, according to the shape of the object to be held in the vise; and E E represent removable staples, which straddle the recesses c, as shown in Fig. 1, for strengthening the jaws and preventing the upper parts thereof. from spreading away from the lower part, as will be understood from said Fig. 2. p j

In using th'e vise it will be understood that the cylinders C C will be set according to the shape of the object to be held, so as to bring the recesses or cavities of the cylinders conforming nearest to the shape of the object to the opening in the faces of the jaws A, sothat when the jaws are brought together for grasping the object it will be held in such recesses or cavities, and held with great firmness and without marring the object.

, Between the cylinders C and the top of the jaws A are formed in the faces ofthe jaws the angular grooves o o, running parallel with the cylinders C, and in these grooves are placed solid triangular bars O O, with iianges o at their ends. The bars O are held in place by the .screws l) p, running through the top of the jaws A at an angle with the ends of the angular bars O.

By removing the bars O the angular grooves ov may be used for the purpose of holding small angular pieces in such manner' that their up-` per corners may be brought up and over the top of the jaws, (if the cylinders C prove too low for the purpose,) so that a plane or* iile may be ru'n over the protruding corner, as in making pins or planing off light pieces of wood, or handles, 8vo.; or very small cylinders similar to the lower cylinders, C, maybe used for the purpose in place of the grooves o and bars O.

Having thus described my invention, what I ICO e :mexico inders being fornied with cavities of various shapes and adapted to be turned in the jaws, substantialljv as and for the purposes described.

2. The combination, with the recessed jaws A, of the cylinders C, torined with the longitudinal and transverse recesses or cavities, i'or holding objects in horizontal and vertical positions, substantially asdescribed.

il. rlhc cylinders C, formed with cavities or recesses and with the llat portions c, substantially as and for the purposes described.

.L. The c vlinders t), placed in recesses inade in the jaws, and t'orined with the narrow slots for holding ilat or edged objects, as set forth. rllhe c vlinders (I, placed iu recesses luade in the jaws, and formed with shallow and short recesses ij, for holding` pointed objects, as set t'orth.

6. The combination, with recessed jaws A and c vlinders C, placed in thejaws, ot'the plates l), for holding the cylinders in place, and i'or preventing the entrance of dust, tvc., substantialljv as described.

rlhe cylinders t", torined with cavities and placed in recesses u., and provided with the l handles b, for revolving the cylinders, substantially as described.

S. rllie combination, with the cylinders C, placed in the recesses a, of the key-pinsel, arranged for holding the cylinders, substantially as set i'orth.

9. The jaws A, having recesses c formed in them, t'or receiving the cylinders C, in combination with the removable staples E, for strengthening tihcj aws audi'or preventing them i'roni spreading, substantially as described.

10. rlhe cylinders C, adapted to be placed and revolved in the recesses a, of tl1e.jaws A., and t'orined with angular cavities or recesses i'or holding angular objects, as set i'ortih.

ll. rllhe c vlinders C, adapted to be placed and revolved in the recessesu, inadein thejaws A, and t'orined with the concaved recesses for holding;` round objects, substantially as seti Vl'orth.
